N2 - The galvanized steel with thickness of 2 mm was joined to 6061 with thickness of 2 mm by laser fusion-brazing process. The filler wire was AlSi5 and wire feed speeds were 2.8, 3.0, and 3.2 m/min, respectively. Microstructure and mechanical properties of the joints were investigated. The Zn-rich zone formed in the area of the seam toe was analyzed by means of optical microscope, scanning electron microscope, and energy-dispersive spectroscopy. Meanwhile, the Fe2Al5Zn0.4phase、Fe(Al,Si)0.5 phase, and Fe(Al,Si)0.7 phase were found at the galvanized steel/brazed metal interface along the weld seam. According to tensile test, the strength of the joints was 31.6 MPa (wire feed speed is 2.8 m/min), 61.4 MPa (3.0 m/min), and 70.4 MPa (3.5 m/min), the failure occurred in interfacial layer at the bottom of the joint.
